When installing LED lights you must take the normal precautions as with any electrical device. Avoid water at all times when working with electricity, avoid wet hands. Never use equipment with damaged or frayed cords/insulation or broken parts such as plugs. If you are working on any open outlet, switch or receptacle always turn off the mains (electricity grid). If people is around or if you have a colleague near, always put a sign on the service panel to avoid someone turning the switch on. Always use insulated tools while working. Be aware of energized equipment, always check that it is de-energized first by using a tester. Always check every wire and metallic cover with the tester before starting to work. If you are going to work on a receptacle at height in your building use a bamboo, wooden or fiberglass ladder avoid using an aluminum or steel one. Know the local wire code. Always check all your Ground Fault Circuit Interrupters or GFCI’s once a month specially in damp areas such as bathrooms or kitchens, GFCIs help avoid electrical shock hazards. If you intend to re-wire directly to the mains, we advise you to contact a qualified electrician. Avoid causing damage to your eyes by staring directly at powerful LED lights. For most LED products, looking at them at close range through a magnifying glass is probably the most dangerous scenario, never do that. LEDs can cause a thermal heating effect in proportion to the power density of the radiation, which can result in tissue damage to the retina. LEDs are actually safer than traditional lighting such as incandescent, halogen or fluorescent fixtures. LEDs are protected against heat-related problems because they usually feature heat sinks that dissipate heat away.
